In addition, the Mac OS X kernel has been rebuilt to run in 64-bit mode on some machines. Apple is also releasing APIs for Grand Central Dispatch for developers to use in their applications and also to analyze specific blocks of code running on Grand Central Dispatch. [46], A new C and Objective-C language feature named "Blocks" facilitates creation of code that will easily optimize to take advantage of Grand Central Dispatch. OpenCL automatically optimizes for the kind of graphics processor in the Mac, adjusting itself to the available processing power. Apart from upgrading, Benjamin also tried a clean install. Despite significant changes in the software, users will experience almost no changes in the user interface. Many of the changes involve how the system works in the background and are not intended to be seen by the user. Use this Guess the Emoji cheat sheet for all the answers to your quizzes. [60], The Safari web browser has received updates to version 6.0 in Lion and Mountain Lion, but not in Snow Leopard. [45] As a result, additional processing power, compared to single-core machines, often goes unused. [41][42] A change to the com.apple.Boot.plist will also enable users with compatible computers to permanently boot into 64-bit for those wishing to do so. [51], CUPS (the printing system used in many Unix-like operating systems) has been updated to version 1.4 which provides improved driver, networking, and Kerberos support along with performance improvements. [39] They will run in 32-bit mode on machines with 32-bit processors, and in 64-bit mode on machines with 64-bit processors. [citation needed]. [58], Computer security researcher Charlie Miller claims that OS X Snow Leopard is more vulnerable to attack than Microsoft Windows for lacking full address space layout randomization (ASLR) since Mac OS X Leopard,[59] a technology that Microsoft started implementing in Windows Vista. This was also the first Mac OS release since System 7.1.1 that does not support Macs using PowerPC processors, as Apple dropped support for them and focused on Intel-based products. [19], Subject to the terms and conditions of this License ... you are granted a limited non-exclusive license to install, use and run one (1) copy of the Apple Software on a single Apple-branded computer at a time.[19]. Vous pouvez vous désabonner en tout temps. For example, the Finder application was completely rewritten in the Cocoa application programming interface. It is not entirely clear which license is offered with the retail version of Snow Leopard. [61], Snow Leopard breaks compatibility with several older versions of some applications, such as Parallels Desktop 3.0, versions of Aperture before 2.1.1, and versions of Keynote before 2.0.2, among other software. There are three licenses available. Grand Central Dispatch abstracts the notion of threads away, and instead provides developers with the concept of queues—lists of jobs (blocks of code) that need to be executed. It serves a similar purpose to Nvidia's C for CUDA and Microsoft's Direct3D 11 compute shaders. [47][48][49], OpenCL (Open Computing Language) addresses the power of graphics processing units (GPUs) to leverage them in any application, and not just for graphics-intensive applications like 3D games. [17] If the system does not possess one of these compatible GPUs, OpenCL code will instead execute on the system's CPU. [65][66][67] This was resolved in 10.6.8. Single-user licenses and "family pack" licenses for up to five computers are available. [16] Reception of Snow Leopard was positive. For qualifying Mac computers bought after June 8, 2009, Apple offered a discounted price through its "up-to-date" program, provided that customers' orders were faxed or postmarked by December 26, 2009. [64] If a native driver is not available Snow Leopard also includes CUPS and Gutenprint open source drivers that may provide limited functionality. An option has been added to the Finder preferences that allows the user to modify search behavior.

Windows can now be minimized directly onto their application's icon in the dock. Furthermore, there are new Apple wallpaper sub-folders with multiple wallpapers: New solid colors can be used as wallpapers as well. There is a new blue and gray, as well as a solid kelp which serves as the "green wallpaper." On the other hand, some Apple press materials appear to indicate that this version is, in fact, the "Single Use" license: The Snow Leopard single user license will be available for a suggested retail price of $29 (US)[20] (emphasis added), However, even if the retail edition of Snow Leopard is in fact a "Leopard Upgrade", the company has acknowledged that there is no technical barrier in that edition preventing a direct upgrade from Mac OS X "Tiger".[21].
